一般的自行車包含有一車架，具有前叉與後叉，分別裝設前輪與後輪。一前齒輪組，具有若干尺寸不同的齒輪，設置於車架上，並與曲柄連接。一後齒輪組，具有若干尺寸不同的齒輪，設置於後輪的輪轂上。一鏈條，連接前齒輪組的一齒輪與後齒輪組的一齒輪。一前變速器，讓騎士控制鏈條於前齒輪組的不同齒輪之間移動；以及一後變速器，讓騎士控制鏈條於後齒輪組的不同齒輪之間移動。 A typical bicycle includes a frame having a front fork and a rear fork, and a front wheel and a rear wheel, respectively. A front gear set having a plurality of gears of different sizes, disposed on the frame and coupled to the crank. A rear gear set having a plurality of gears of different sizes disposed on the hub of the rear wheel. A chain connecting a gear of the front gear set with a gear of the rear gear set. A front derailleur allows the knight to control the chain to move between the different gears of the front gear set; and a rear derailleur allows the knight to control the chain to move between the different gears of the rear gear set.
變速器的使用在於讓騎士可依據路況的不同而調整不同的齒輪比。例如：當行使於上坡時，可將鏈條移動至前齒輪組的小齒輪且/或前齒輪組的大齒輪，以得到較小的齒輪比；當行使於下坡時，可將鏈條移動至前齒輪組的大齒輪且/或前齒輪組的小齒輪，以得到較大的齒輪比。 The use of the transmission is to allow the Cavaliers to adjust different gear ratios depending on the road conditions. For example, when exercising on an uphill slope, the chain can be moved to the pinion of the front gear set and/or the large gear of the front gear set to obtain a smaller gear ratio; when exercising on a downhill slope, the chain can be moved to The large gear of the front gear set and/or the pinion of the front gear set to achieve a larger gear ratio.

請參閱圖1所示，本發明一較佳實施例所提供之自動變速自行車，包含有：一車架10、一前輪12以及一後輪14，分別樞設於該車架10、二曲柄16(圖中僅顯示一個曲柄16)、二踏板18(圖中僅顯示一個踏板18)，設置於各該曲柄16的外端、一主傳動裝置，包括：一前齒輪22、一後齒輪24設置於後輪14以及一鏈條26，圈繞於前齒輪22與後齒輪24，用以將動力傳輸至後輪14，以及一自動變速器28。除自動變速器28外，其餘之構件與一般自行車相同，在此容不贅述。 Referring to FIG. 1 , an automatic shift bicycle provided by a preferred embodiment of the present invention includes: a frame 10 , a front wheel 12 and a rear wheel 14 respectively pivoted to the frame 10 and the two cranks 16 . (only one crank 16 is shown in the figure), two pedals 18 (only one pedal 18 is shown in the figure), which are disposed at the outer end of each of the cranks 16 and a main transmission device, including: a front gear 22 and a rear gear 24 The rear wheel 14 and a chain 26 are wound around the front gear 22 and the rear gear 24 for transmitting power to the rear wheel 14, and an automatic transmission 28. Except for the automatic transmission 28, the rest of the components are the same as those of the general bicycle, and will not be described here.
請參閱圖2至圖5所示，該自動變速器28包括：一外殼30，由二半殼組合而成，固定於車架10上。該外殼30中設置有一第一軸32、一第一輪42、一第二軸50、一第二輪54、一皮帶58以及一惰輪60。該第一軸32的兩端伸出該外殼30，以連接該二曲柄16。藉此，騎士踩踏踏板18可經由曲柄16 轉動該第一軸32。該第一軸32上更設置有一軸套34，可相對於該第一軸32自由轉動。該軸套34上設置有一齒輪36以及該前齒輪22，其中該前齒輪22位於該外殼30的外側，該齒輪36位於該外殼30之中。 Referring to FIGS. 2 to 5, the automatic transmission 28 includes a casing 30 which is assembled from two halves and is fixed to the frame 10. A first shaft 32, a first wheel 42, a second shaft 50, a second wheel 54, a belt 58 and an idler 60 are disposed in the outer casing 30. Both ends of the first shaft 32 extend out of the outer casing 30 to connect the two cranks 16. Thereby, the knight can step on the pedal 18 via the crank 16 The first shaft 32 is rotated. The first shaft 32 is further provided with a sleeve 34 that is free to rotate relative to the first shaft 32. The sleeve 34 is provided with a gear 36 and the front gear 22, wherein the front gear 22 is located outside the outer casing 30, and the gear 36 is located in the outer casing 30.
該第一輪42具有一固定碟44以及一活動碟46。該固定碟44固設於該第一軸32上，可隨著該第一軸32轉動，但無法沿該第一軸32的軸向移動。該活動碟46的軸孔461的壁面上設置有交替的凸塊與凹槽，該第一軸32上亦有沿軸向延伸且呈對應的凹槽與凸塊，讓該活動碟46設置於該第一軸32上可隨著該第一軸32轉動，並沿該第一軸32的軸向移動。該固定碟44較該活動碟46靠近該軸套34。在該第一軸32上更設有一基座38以及一彈簧40。該彈簧40套設於該第一軸32上，兩端分別抵靠該基座38與該活動碟46，藉以推動該活動碟46朝向該固定碟44的方向移動。該固定碟44與該活動碟46相對之一側上分別具有一凸出的錐狀面48。藉此，該固定碟44與該活動碟46之間的距離為由軸心向邊緣逐漸增加。 The first wheel 42 has a fixed disk 44 and a movable disk 46. The fixed disc 44 is fixed to the first shaft 32 and is rotatable along the first shaft 32 but is not movable in the axial direction of the first shaft 32. The movable hole 46 is provided with alternating protrusions and grooves on the wall surface of the shaft hole 461. The first shaft 32 also has axial grooves and corresponding grooves and projections for the movable disk 46 to be disposed on the wall. The first shaft 32 is rotatable with the first shaft 32 and moves along the axial direction of the first shaft 32. The fixed disc 44 is closer to the sleeve 34 than the movable disc 46. A base 38 and a spring 40 are further disposed on the first shaft 32. The spring 40 is sleeved on the first shaft 32, and the two ends abut against the base 38 and the movable disc 46 respectively, thereby pushing the movable disc 46 to move toward the fixed disc 44. The fixed disc 44 has a convex tapered surface 48 on one side opposite to the movable disc 46. Thereby, the distance between the fixed dish 44 and the movable dish 46 is gradually increased from the axis to the edge.
該第二軸50的兩端分別樞設於該外殼30，使其可自由轉動。該第二軸50上固設有一齒輪52，與該軸套34上的齒輪36對應，且二齒輪36、52由一鏈條56連接，藉此該第二軸50的轉動可帶動該軸套34轉動。該第二輪54設置於該第二軸50上，可隨著該第二軸50轉動，並沿該第二軸50的軸向移動。如同第一軸32與活動碟46一樣，在第二軸50與第二 輪54的軸孔541上分別設置有對應的凸塊與凹槽，以達成第二輪54轉動與移動的功能。該第二輪54上設置有二環形牆542，該二環形牆542之間可供該皮帶58套設。 Both ends of the second shaft 50 are respectively pivotally mounted on the outer casing 30 so as to be freely rotatable. A gear 52 is fixed on the second shaft 50, corresponding to the gear 36 on the sleeve 34, and the two gears 36, 52 are connected by a chain 56, whereby the rotation of the second shaft 50 can drive the sleeve 34. Turn. The second wheel 54 is disposed on the second shaft 50 and is rotatable along the second shaft 50 and moves along the axial direction of the second shaft 50. As with the first shaft 32 and the movable disc 46, the second shaft 50 and the second Corresponding protrusions and grooves are respectively disposed on the shaft holes 541 of the wheel 54 to achieve the function of rotating and moving the second wheel 54. The second wheel 54 is provided with two annular walls 542, and the belt 58 can be sleeved between the two annular walls 542.
該皮帶58具有彈性，套設於該第一輪42與該第二輪54上。該皮帶58的斷面呈梯形，皮帶58外側的寬度大於皮帶58內側，且兩側面的斜率配合該固定碟44與該活動碟46的錐狀面48。由於該彈簧40的作用，該皮帶58會被夾在該固定碟44與該活動碟46的錐狀面48之間，並由於摩擦力的作用，使該固定碟44與該活動碟46的轉動會帶動該皮帶58轉動。 The belt 58 has elasticity and is sleeved on the first wheel 42 and the second wheel 54. The belt 58 has a trapezoidal cross section, the outer side of the belt 58 has a width greater than the inner side of the belt 58, and the slopes of the two sides cooperate with the fixed disc 44 and the tapered surface 48 of the movable disc 46. Due to the action of the spring 40, the belt 58 is sandwiched between the fixed disc 44 and the tapered surface 48 of the movable disc 46, and the rotation of the fixed disc 44 and the movable disc 46 is caused by the frictional force. The belt 58 will be rotated.
該惰輪60的一端樞設於該外殼30的內側面，另一端則抵靠於該皮帶58，以調整皮帶58的張力。 One end of the idler 60 is pivotally disposed on the inner side of the outer casing 30, and the other end abuts against the belt 58 to adjust the tension of the belt 58.
彈簧40、皮帶58與惰輪60之間應有特定的關係，讓自動變速器28在初始狀態下，該皮帶58是位在遠離該第一輪42的軸心的位置。在此領域中具有通常知識者可輕易找出其組合。在此定義由皮帶58與第一輪42軸心之間的距離為該第一輪42的有效半徑Reff。 There should be a particular relationship between the spring 40, the belt 58 and the idler gear 60 such that the belt 58 is in a position away from the axis of the first wheel 42 in the initial state. Those with ordinary knowledge in this field can easily find out their combination. Here, the distance between the belt 58 and the axis of the first wheel 42 is defined as the effective radius Reff of the first wheel 42.
當騎士踩踏踏板18時，動力會經由曲柄16、第一軸32、第一輪42而帶動皮帶58轉動，接著皮帶58再帶動第二輪54轉動。該第二輪54的轉動透過一次傳動裝置(第二軸50上之齒輪52、鏈條56與第一軸32上之齒輪36)帶動軸套34轉動，最後再帶動該前齒輪22轉動，以驅動自行車前進。該第一輪 42的有效半徑Reff與該第二輪54的半徑，則提供除前齒輪22與後齒輪24外的另一次速度與扭力的變換。 When the knight steps on the pedal 18, the power will drive the belt 58 to rotate via the crank 16, the first shaft 32, and the first wheel 42, and then the belt 58 drives the second wheel 54 to rotate. The rotation of the second wheel 54 drives the sleeve 34 to rotate through the primary transmission (the gear 52 on the second shaft 50, the chain 56 and the gear 36 on the first shaft 32), and finally drives the front gear 22 to rotate to drive The bicycle is moving forward. The first round The effective radius Reffe of 42 and the radius of the second wheel 54 provide a change in speed and torque other than the front gear 22 and the rear gear 24.
當騎士踩踏踏板18的過程中，會施予該第一軸32一扭力，而此扭力會沿該固定碟44與該活動碟46而傳遞至皮帶58，致使皮帶58的張力改變(增大)。請參閱圖6與圖7所示，在未踩踏踏板18，或是自行車行駛於下坡，騎士所提供的扭力小於某一預定值時，皮帶58是位於在遠離該第一輪42的軸心的位置，此時該第一輪42的有效半徑Reff大於該第二輪54的半徑。再請參閱圖8與圖9，當自行車由停止開始行駛，或是行駛於上坡時，此時騎士會以一較大的力量踩踏踏板18，以產生一扭力，經由曲柄16、第一軸32、該固定碟44與該活動碟46而傳遞至皮帶58，致使皮帶58的張力增加。此時，皮帶58的張力會大於彈簧40的彈力，藉由二錐狀面48的作用，該皮帶58會將該活動碟46往遠離該固定碟44的方向推離，並壓縮彈簧40，造成兩錐狀面48之間的距離增加，使得該皮帶58往第一輪42的軸心移動，使該第一輪42的有效半徑Reff減小。可輕易了解的是，當騎士踩踏踏板的力量愈大時，皮帶58的張力亦愈大，皮帶58的張力愈大，會使得活動碟46愈離開固定碟44，且使皮帶58愈往第一輪42的軸心移動。結論是，騎士踩踏踏板18的力量(或稱作用於該第一軸32的扭力)與第一輪42的有效半徑Reff成反比。當自行車由停止開始行駛，或是行駛於上坡時，騎士踩踏踏板18的力量愈大(作 用於該第一軸32的扭力愈大)，第一輪42的有效半徑Reff減小，使第一輪42與第二輪54間的輪徑比降低，如此騎士可以較省力(低速檔)的方式騎乘自行車。相反的，當自行車行駛於下坡，或於高速滑行時，騎士踩踏踏板的力量減小(作用於該第一軸32的扭力降低)，第一輪42的有效半徑Reff增加，使第一輪42與第二輪54間的輪徑比增加，如此騎士可以較有效率(高速檔)的方式騎乘自行車。 When the knight steps on the pedal 18, the first shaft 32 is biased, and the torque is transmitted to the belt 58 along the fixed disc 44 and the movable disc 46, causing the tension of the belt 58 to change (increase). . Referring to FIGS. 6 and 7, the belt 58 is located at an axis away from the first wheel 42 when the pedal 18 is not stepped on, or the bicycle is traveling downhill, and the torque provided by the knight is less than a predetermined value. The position of the first wheel 42 is greater than the radius of the second wheel 54. Referring again to FIG. 8 and FIG. 9, when the bicycle starts to stop or travels uphill, the knight will step on the pedal 18 with a large force to generate a torque through the crank 16, the first shaft. 32. The fixed disc 44 and the movable disc 46 are transferred to the belt 58, causing the tension of the belt 58 to increase. At this time, the tension of the belt 58 will be greater than the elastic force of the spring 40. By the action of the two-tapered surface 48, the belt 58 will push the movable disc 46 away from the fixed disc 44 and compress the spring 40, resulting in The distance between the two tapered faces 48 is increased such that the belt 58 moves toward the axis of the first wheel 42 such that the effective radius Reff of the first wheel 42 decreases. It can be easily understood that the greater the strength of the belt when the knight steps on the pedal, the greater the tension of the belt 58, and the greater the tension of the belt 58, the more the movable disc 46 leaves the fixed disc 44, and the belt 58 becomes more first. The axis of the wheel 42 moves. The conclusion is that the force the knight steps on the pedal 18 (or the torque for the first shaft 32) is inversely proportional to the effective radius Reff of the first wheel 42. When the bicycle starts to stop or is driving uphill, the greater the knight’s power to step on the pedal 18 The greater the torque for the first shaft 32, the effective radius Reff of the first wheel 42 is reduced, so that the wheel-to-diameter ratio between the first wheel 42 and the second wheel 54 is reduced, so that the knight can be labor-saving (low gear). Way to ride a bicycle. Conversely, when the bicycle is traveling downhill or at high speed, the strength of the knight pedaling is reduced (the torque acting on the first shaft 32 is reduced), and the effective radius Reff of the first wheel 42 is increased to make the first round The wheel-to-diameter ratio between 42 and the second wheel 54 is increased, so that the rider can ride the bicycle more efficiently (high-speed).
在此要提出說明的是，當活動碟46向外移動，使皮帶58往第一輪42的軸心移動時，因為錐狀面48的因素，皮帶也會產生沿第一軸32軸向的位移，此時可沿第二軸50移動的第二輪54，會自動隨著皮帶58的位移而移動，使皮帶58的傳動能順利進行。另外，該皮帶58的選擇最好以皮帶58在兩側面(皮帶接觸間固定碟44與活動碟46之處)間的方向具有較低的可撓性，而垂直於此方向具有較大的可撓性。 It is to be noted here that when the movable disk 46 is moved outward to move the belt 58 toward the axis of the first wheel 42, the belt is also axially generated along the first axis 32 due to the factor of the tapered surface 48. The displacement, at this time, the second wheel 54, which is movable along the second shaft 50, will automatically move with the displacement of the belt 58, so that the transmission of the belt 58 can proceed smoothly. In addition, the belt 58 is preferably selected to have a lower flexibility in the direction between the belt 58 on both sides (where the belt contacts hold the disc 44 and the movable disc 46), and has a larger vertical direction in this direction. flexibility.
總結以上，本發明所提供之自動變速器28，可根據騎士踩踏踏板18的力量而自動變速，以提供其是一種有效率的騎乘自行車的方式，而無需騎士自己操作變速器。 In summary, the automatic transmission 28 of the present invention can be automatically shifted according to the force of the knight pedaling the pedal 18 to provide an efficient way to ride the bicycle without requiring the rider to operate the transmission himself.
在本發明實施例中，我們提供固定碟、活動碟、彈簧、具有彈性的皮帶為本發明的自動調整手段，實務上，任何可依據踩踏踏板的力量而自動改變第一輪之有效半徑的手段，例如第一輪以使用具有彈性的材料製成，使皮帶的張力可壓縮第一輪，均可應用於本發明。 In the embodiment of the present invention, we provide a fixed disc, a movable disc, a spring, and an elastic belt as the automatic adjusting means of the present invention.
